Some scholars believe that the Creed promulgated by the First Ecumenical Council was based on an earlier baptismal creed used in Palestine, while others regard its more likely origin as being a creed issued early in 325 A.D. in Antioch, a so-called "Syrian Creed."

The Creed of Nicea (325 A.D.)

We believe in one God, the Father almighty, maker of all things, visible and invisible;

And in one Lord Jesus Christ, the Son of God, begotten froom the Father, only-begotten, that is, from the essence of the Father, God from God, light from light, true God from true God, begotten not made, of one essence with the Father, through Whom all things came into being, things in heaven and things on earth, Who because of us men and because of our salvation came down and became incarnate, becoming man, suffered and rose again on the third day, ascended to the heavens, and will come again to judge the living and the dead;

And in the Holy Spirit.

The Nicene-Constantinopolitan Creed (381 A.D.)

In English:

We believe in one God, the Father Almighty, Maker of heaven and earth, and of all things visible and invisible;

And in one Lord Jesus Christ, the Son of God, the Only-begotten, Begotten of the Father before all worlds, Light of Light, Very God of Very God, Begotten, not made; of one essence with the Father, by whom all things were made:

Who for us men and for our salvation came down from heaven, and was incarnate of the Holy Spirit and the Virgin Mary, and was made man;

And was crucified also for us under Pontius Pilate, and suffered and was buried;

And the third day He rose again, according to the Scriptures;

And ascended into heaven, and sitteth at the right hand of the Father;

And He shall come again with glory to judge the quick and the dead, Whose kingdom shall have no end.

And we believe in the Holy Spirit, the Lord, and Giver of Life, Who proceedeth from the Father, Who with the Father and the Son together is worshipped and glorified, Who spake by the Prophets;
